Join us for a virtual discussion with guest speakers from NASA GLOBE to learn why trees and tree height are so important to NASA, California, and the entire planet. You will find out how to participate in the 2021 GLOBE Community Trees Challenge to help NASA scientists further their research using your mobile device and a simple instrument called a clinometer. You will also learn to build a hand-held clinometer using everyday materials. This family-friendly program is suitable for ages 8 and up.
